Application i1ed January 21, 1909. Serial No. l173,456.

To all whom it may concern.'`

Be it.- known that I, llniiviNL. STONE, residing at Lewiston, in the county of Androseog'gin and State of Maine. have invented 5 certain new and useful Improvements in Yeft-Replenishing Looms; of which the following is a specific-ation.

'.lhe object of the present inventionis to provide means for taking' eare of the weft- 1,0 ends of weft-carriers while occupying the magazine of a weft-replenishing loom and until each weftcarrier is transferred into weaving position in the loom.

'One embodiment' of the present invention is shown in the ,accompanying drawings,`

wherein Figure l, is a side view of the improved mechanism. Fig. 2. is a plan View of a part thereof. Fig. 3, is vcross section. Fig'. 4, is a detail of one of the weft-carriers.

rPhe drawings illustrate ,only so much of the loom as is necessarir for au understanding of the invention.

The loom has a transferrer A, which acts to transfer a weft-carrier B. from the magazine for spare weft-Carriers into weaving' p0- sition in the loom. This transferrer is like that employed in the now well-known Northrop loom and is shown. for example, iu

-lhe illustrated magazine is one, which Carries and holds a staelt or column of superimposed weft-earriers. As shown it has a guide channel (l. for the weft-carrier butts which prevents anvsubstantial endwise movement of the wefta'arriers; and it has a fluide or support D, 'for the weft-carrier tips. rl`he active weft-earrier is stopped at the transfer 40 point in cooperative relation with the transferrer A. by stops C, and F.

.llaeh weft-carrier has its own weft-end holder (i. which is detaehablv held thereon. Each holder has a stem H, fitting' the hollow of the carrier tip; and also has a reeess l.. with a notch J, for ysecuringr the weft-end. lith thiseonstrnction the weft-end foreach carrier is properly helld in place while the weft-carrier occupies t'he magazine, and until itv is transferred into weaving position.

The special object of the present invention is to remove the'se detachable holders G,-

Afed to the transfer point.

from their carriers prior to the transfer of each carrier into weaving position. 'To this endl there is a cam-track K, alongside the tip-guidey D.-which engages the holders G. As the carriers advance in the magazine toward the transfer point their holders enter the eamtraelL and during their further advaure. the holders are rammed outwardly until they are wholly freed from their car.- riers. "he gruide-elniunel C, prevents any substantial eudwise movement of the carriers during'v the eauuning' out of the holders. Each holder has the same diameter as the carrier butt. so that after detachment the holders advance equally with the carriers.' Each holder is whollv detached froln its carrier before the transfer point is reached, so that the carrier is there read \1 for the transfer; but the holder remainsin position holding onto the weft-end until after the transfer. so that the weft pays out during' the first tiipht of the transferred carrier through the shed. The rain-track extends beyond the transfer point. Aand eventuall)Y the detached holders are discharged therefrom into an \y suitable reeeivtn'.

Desirabl)Y the weft should be slael between holder and r'arrie'.' at the Itime of transfer. '.l`o serure thisv slarliness. the ram-track has an inwardly extending' path li. whieh movesl the detaehed holder toward its earrieixthhs slaclrening the weft-end.

'lti aid in feeding' the column of weft-carriers in the magazine. and the outward eamming; of the holders. a weight- M. is employed whieh forros theI we ft-earriers along.
